2.5 Power Supply
+12V primary power supply input
+5V standby
Option, is not required for module operation.
If not present, customer must ensure that the supply voltages which are generated on the
carrier board are switched off during suspend states, so that no current from the carrier
board’s signal lines can flow to the CPU board.
3.3V RTC power supply
Option, is not required for module operation.
BIOS SETUP data is stored in a nonvolatile backup memory device, therefore configuration
data will not get lost after power removal (except for time and date information)

Running Mode
All measurements were made by plugging the MSC CXC-BT module onto a
MSC MB-EVA2
carrier. The module was equipped with two 4GByte memory modules Hynix
HMT351S6EFR8A-PB N0 AA,
4GB 2Rx8 PC3L-12800S-11-12-F3. The table below shows
typical values which refer to consumption of the module itself without consumption of the
base board and CPU fan.
The following applications have been tested.
1. DOS prompt.
2. Windows desktop (idle) under Microsoft Windows 7 Professional 64-bit SP1.
3. Running Intel® Thermal Analysis Tool (TAT) Ver. 5.x to achieve 100% CPU workload on
each processor core/thread, 100% Graphics workload and 100% Memory Read Stress
workload under Microsoft Windows 7 Professional 64-bit SP1.
